[0052] With the improvement of living standards, people have higher and higher requirements for indoor air quality and comfort, requiring not only the indoor air temperature to be within an appropriate range, but also the indoor air humidity to be within an appropriate range. A humidifier can adjust the humidity of indoor air to meet the user's demand for indoor air comfort. In the related art, a humidifier includes a water tank, an air inlet, a mist outlet assembly and a micro switch, wherein the air inlet is located between the water tank and the mist outlet assembly, and the micro switch is arranged on the surface of the air inlet to control the humidifier to be powered on or off through the micro switch. However, in the related art, the micro switch is easily exposed to dust particles or liquids, resulting in a technical problem of low working reliability of the micro switch.

[0053] In order to solve the above problems, an embodiment of the present application provides a humidifier, by designing a accommodating cavity on the air inlet member, and setting the contact switch in the accommodating cavity, the trigger mechanism is movably arranged at the position of the air inlet member corresponding to the contact switch, and the driving mechanism can drive the trigger mechanism to move in the direction close to the contact switch to trigger the contact switch through the trigger mechanism; in this way, the contact switch is always located in an independent accommodating cavity, which can prevent external dust particles from causing the contact switch to get stuck, and can prevent liquid or humid air from increasing the risk of damage to the contact switch, thereby improving the working reliability of the contact switch and extending the service life of the contact switch.

[0054] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0055] An embodiment of the present application provides a humidifier, which includes but is not limited to a fogless humidifier.

[0056] The structure of the humidifier will be described in detail below by taking a fogless humidifier as an example in conjunction with the accompanying drawings.

[0057] Please refer to Figure 1 As shown, the humidifier 100 provided in the embodiment of the present application includes a water tank 110, an air inlet assembly 120 and an air outlet assembly 140, wherein the air inlet assembly 120 is arranged on the water tank 110, and the air outlet assembly 140 is arranged on the air inlet assembly 120, and the water tank 110 has a water storage cavity for storing humidification water of the humidifier 100. The humidification water in the water tank 110 may be pure water, or may be an aqueous solution with additives such as mixed spices, bactericides, essential oils, etc., which is not specifically limited in the embodiment of the present application, and the liquid in the water tank 110 is collectively referred to as water below, and no specific description is given.

[0058] In some embodiments, the water tank 110 has a water pump and a filter 111, and the water pump is used to pump water in the water tank 110 to the filter 111 to humidify the filter 111. The air inlet assembly 120 includes an air inlet member 121 and a contact switch 122, and the air inlet member 121 has an air inlet mesh connected to the water tank 110. The air outlet assembly 140 includes an air duct 141, a motor 142, a fan 143 and an air outlet net 144. The air duct 141 is connected to the air inlet mesh, the fan 143 is connected to the motor 142 and is arranged in the air duct 141, the air outlet net 144 is arranged at the air outlet end of the air duct 141, and the contact switch 122 is electrically connected to the motor 142 to control the on and off of the motor 142; in this way, when the fan 143 runs at a high speed, the air flow is discharged to the outside air through the water tank 110, the air inlet mesh, the air duct 141 and the air outlet net 144 holes in sequence, and the high-speed operation of the fan 143 can accelerate the evaporation of water on the filter 111, so that the air flow discharged from the humidifier 100 to the outside air carries a large amount of water molecules, so that the water molecules in the air are increased, thereby achieving the purpose of air humidity; and the humidification is more uniform, without white mist pollution, tap water can be directly added to the water tank 110, the humidity control is relatively stable, and the user's comfort is improved.

[0059] In some embodiments, please refer to Figure 2 As shown, the air outlet assembly 140 also includes a shell 145, a motor bracket 146, a fan nut 147 and a knob switch 148. The air duct 141 is arranged in the shell 145. The motor 142 is fixed to the motor bracket 146 by screws, for example. The fan 143 is installed on the motor 142 and fixed by the fan nut 147. In addition, the motor bracket 146 is fixed to the shell 145 by screws, for example, and the air outlet net 144 is buckled on the shell 145. The knob switch 148 is set on the air outlet net 144. When the fan 143 is running, it can drive the air flow, and the air outlet size of the humidifier 100 can be adjusted by the knob switch 148. For details, please refer to the relevant technology and will not be described in detail here.

[0060] In order to prevent dust particles and liquids from affecting the working reliability of the micro switch, in the embodiment of the present application, please refer to Figure 3 As shown, the air inlet member 121 has a accommodating cavity 1211, and the contact switch 122 is arranged in the accommodating cavity 1211; the air inlet assembly 120 also includes a trigger mechanism 123, the trigger mechanism 123 is movably arranged on the air inlet member 121, and is at least partially located in the accommodating cavity 1211, and is arranged at a position corresponding to the contact switch 122, so that the trigger mechanism 123 can move toward the contact switch 122 under the action of a force to trigger the contact switch 122.

[0061] It should be noted that the accommodating cavity 1211 is an independent space. In this way, setting the contact switch 122 in the accommodating cavity 1211 can prevent dust particles from entering the contact switch 122 and causing it to get stuck, and can also prevent water or humid air from coming into contact with the contact switch 122 and causing the contact switch 122 to malfunction and fail to work.

[0062] In some embodiments, Figure 4 As shown in , the air inlet member 121 includes an air inlet body 1212 and a cover 1213. The air inlet body 1212 has a receiving groove extending toward one side of the water tank 110. The cover 1213 is detachably connected to the notch of the receiving groove. The cover 1213 and the receiving groove are jointly enclosed to form an independent receiving chamber 1211. The contact switch 122 is located in the receiving chamber 1211. In this way, by making the air inlet body 1212 and the cover 1213 detachably connected, it is convenient to maintain or replace the contact switch 122 in the receiving chamber 1211.

[0063] The cover 1213 and the air inlet body 1212 may be detachably connected by means of, for example, snap connection, magnetic connection or threaded connection, which is not specifically limited herein.

[0064] In some embodiments, the contact switch 122 is, for example, a micro switch. Figure 3 and Figure 4 As shown in the figure, the contact switch 122 has a contact spring 1221, and a contact point is provided at a position on the contact switch 122 corresponding to the contact spring 1221. In this way, when the trigger mechanism 123 moves toward the contact switch 122, it can push the contact spring 1221 to move so that the contact spring 1221 contacts the contact point, thereby achieving the purpose of triggering the contact switch 122.

[0065] In some embodiments, the humidifier 100 further includes a driving mechanism 130 , which is configured to drive the trigger mechanism 123 to move toward a direction close to the contact switch 122 to trigger the contact switch 122 .

[0066] Among them, the driving mechanism 130 can be an electrically controlled driving mechanism 130 or a mechanical driving mechanism 130. When the driving mechanism 130 is an electrically controlled driving mechanism 130, the driving mechanism 130 can drive the trigger mechanism 123 to move according to the electrical control signal; when the driving mechanism 130 is a mechanical driving mechanism 130, the trigger mechanism 123 can be driven by external force to trigger the contact switch 122. Specifically, adaptive selection can be made according to actual needs.

[0067] In some embodiments, the driving mechanism 130 is disposed outside the accommodating cavity 1211, for example, the driving mechanism 130 is disposed in the water tank 110. The air inlet 121 has a through hole 1214 connecting the water tank 110 and the accommodating cavity 1211, and the trigger mechanism 123 is disposed in the through hole 1214 and can move up and down along the through hole 1214.

[0068] like Figure 5 As shown in the figure, the contact switch 122 is fixed in the accommodating cavity 1211, and the contact spring 1221 faces the side of the water tank 110, and the side of the air outlet member facing the water tank 110 has a through hole 1214 connected to the accommodating cavity 1211, and the trigger mechanism 123 is arranged in the through hole 1214, and can move along the through hole 1214 toward the contact switch 122 under the action of, for example, a driving mechanism 130, so that the contact spring 1221 contacts with the contact contact, thereby achieving the purpose of triggering the contact switch 122.

[0069] It can be understood that by setting the driving mechanism 130 in the water tank 110, the driving mechanism 130 can drive the trigger mechanism 123 to move up and down along the through hole 1214 in the through hole 1214 to trigger the contact switch 122. In this way, the compactness of the overall structure of the humidifier 100 is improved while preventing the contact switch 122 from contacting liquids such as water.

[0070] In some embodiments, the humidifier 100 further includes a float mechanism, which is configured to move up and down in a vertical direction in the water tank 110 , and the float mechanism is formed as the driving mechanism 130 .

[0071] It can be understood that the float mechanism can float on the surface of the water by the buoyancy of the water in the water tank 110. In this way, the rise and fall of the water level in the water tank 110 will cause the float mechanism to rise and fall in the vertical direction. In this way, the float mechanism is used as the driving mechanism 130 and is arranged below the trigger mechanism 123 (such as Figure 6 and Figure 7 When the water level of the water tank 110 rises, the float mechanism can rise vertically to push the trigger mechanism 123 to move toward the contact switch 122 to trigger the contact switch 122 (as shown in FIG. Figure 8 and Fig. 9 As the water level in the water tank 110 drops, the float mechanism drops in the vertical direction, and the trigger mechanism 123 moves away from the contact switch 122 under the action of its own gravity, so that the contact switch 122 is automatically powered off, and the humidifier 100 automatically stops working, avoiding the potential safety hazard caused by the humidifier 100 still running when there is no water in the water tank 110.

[0072] It can be seen that in the embodiment of the present application, by using the float mechanism as the driving mechanism 130, the float mechanism is raised and lowered according to the height of the water level in the water tank 110, so that the trigger mechanism 123 moves toward or away from the contact switch 122, and there is no need to set up an additional driving mechanism 130. The structure is simple, the cost is low, the safety and reliability are high, and it is environmentally friendly and energy-saving, which improves the user experience.

[0073] In some embodiments, please refer to Fig.10 and Fig.11 As shown, one end of the trigger mechanism 123 has a first limiting portion 1242, and the other end of the trigger mechanism 123 has a second limiting portion 1252. The first limiting portion 1242 and the second limiting portion 1252 are respectively located at opposite ends of the through hole 1214, and the projection area of ​​the first limiting portion 1242 and the second limiting portion 1252 in the vertical direction is larger than the projection area of ​​the through hole 1214 in the vertical direction. In this way, the trigger mechanism 123 can be prevented from falling off from the through hole 1214 by limiting the first limiting portion 1242 and the second limiting portion 1252, thereby improving the position reliability of the trigger mechanism 123.

[0074] For example, Fig.10 and Fig.11 As shown in the figure, the first limiting portion 1242 is the first limiting baffle, and the second limiting portion 1252 is the second limiting baffle. In addition to limiting the trigger mechanism 123 to prevent the trigger mechanism 123 from falling off from the through hole 1214, the first limiting baffle and the second limiting baffle can also prevent dust particles, water, etc. from entering the accommodating cavity 1211 to further improve the working reliability of the contact switch 122.

[0075] For example, the first limiting portion 1242 is arranged at one end of the trigger mechanism 123 toward the driving mechanism 130, and the second limiting portion 1252 is arranged at one end of the trigger mechanism 123 toward the contact switch 122. In this way, the driving mechanism 130 applies force to the first limiting portion 1242 to move the trigger mechanism 123 toward the contact switch 122, so that the second limiting portion 1252 triggers the contact switch 122.

[0076] In some embodiments, please refer to Fig.11 As shown, the trigger mechanism 123 includes a first trigger and a second trigger member 125, the first trigger member 124 includes a first connection portion 1241 and a first limit portion 1242; the second trigger member 125 includes a second connection portion 1251 and a second limit portion 1252, and the first connection portion 1241 and the second connection portion 1251 are configured to penetrate the through hole 1214 and be detachably connected. In this way, by making the first trigger member 124 and the second trigger member 125 detachably connected, the trigger mechanism 123 can be installed in the through hole 1214 or removed from the through hole 1214.

[0077] In some embodiments, the first connection portion 1241 has a first buckling structure 1243, and the second connection portion 1251 has a second buckling structure 1253 matching the first buckling structure 1243, and the first buckling structure 1243 is buckled with the second buckling structure 1253 to connect the first connection portion 1241 and the second connection portion 1251. In this way, the first connection portion 1241 and the second connection portion 1251 are buckled to achieve a detachable connection between the first trigger member 124 and the second trigger member 125, which has a simple structure and low cost.

[0078] In some embodiments, the end of the first connecting portion 1241 facing away from the first limiting portion 1242 has an elastic snap, and the end of the second connecting portion 1251 facing away from the second limiting portion 1252 has a socket for the first connecting portion 1241 to be inserted, and the hole wall has a slot connected to the socket, and the elastic snap is configured to be engaged with the slot via the socket; in this way, the first connecting portion 1241 and the second connecting portion 1251 are facilitated to be disassembled and assembled by means of the elastic snap and the slot, while improving the connection reliability of the first trigger member 124 and the second trigger member 125.

[0079] For example, Fig.10 and Fig.11 As shown, there are two elastic clips, and the two elastic clips are symmetrically arranged with respect to the axis of the extension direction of the first connection part 1241, and there is an elastic gap between the two elastic clips; there are respectively provided with slots at positions corresponding to the two elastic clips on the hole wall of the insertion hole, so that when the first connection part 1241 and the second connection part 1251 are connected, the two elastic clips on the first connection part 1241 pass through the insertion hole on the second connection part 1251 and are respectively engaged with the corresponding slots, thereby improving the connection reliability and disassembly convenience of the first trigger member 124 and the second trigger member 125.

[0080] In other embodiments, the first connection portion 1241 has a first magnetic member, the second connection portion 1251 has a second magnetic member, and the first magnetic member and the second magnetic member are magnetically attracted to each other to connect the first connection portion 1241 with the second connection portion 1251. In this way, the first trigger member 124 and the second trigger member 125 are detachably connected by magnetism, and the disassembly and assembly method is simple and low in cost.

[0081] Exemplarily, the first magnetic member and the second magnetic member may both be magnets; or, one of the first magnetic member and the second magnetic member is a magnet, and the other is made of a material that can be magnetically attracted by a magnet, and no specific limitation is made here.

[0082] In some embodiments, Fig.12As shown, the float mechanism may include a float 131 , and one end of the float 131 facing the air outlet has a driving portion, and the driving portion is, for example, a rod-shaped structure, so as to drive the trigger mechanism 123 through the driving portion.

[0083] The float 131 may be made of a material that can float on the water surface, which is not limited here.

[0084] In addition, please continue to refer to Fig.12 As shown, the float mechanism also includes a float bracket 132, and the float bracket 132 has a lifting space for the float 131 to rise and fall. The float bracket 132 is arranged in the water tank 110 and is immovable relative to the water tank 110. The float 131 floats in the lifting space of the float bracket 132 under the buoyancy of water. In this way, the float 131 can be limited in the circumferential direction to prevent the float 131 from moving in the circumferential direction and failing to drive the trigger mechanism 123, thereby improving the accuracy and reliability of the float 131 driving the trigger mechanism 123.

[0085] In some embodiments, the filter 111 disposed in the water tank 110 forms an annular structure, so that the area of ​​the filter 111 can be increased, thereby improving the humidification efficiency of the humidifier 100. The float mechanism is located in the annular structure of the filter 111, so that the utilization rate of the space in the water tank 110 can be improved, thereby improving the compactness of the overall structure of the humidifier 100.

[0086] The humidifier provided in the embodiment of the present application is provided with a accommodating chamber in the air inlet member, and the contact switch is provided in the accommodating chamber. The trigger mechanism is movably provided at a position of the air inlet member corresponding to the contact switch, and the driving mechanism can drive the trigger mechanism to move in a direction close to the contact switch so as to trigger the contact switch through the trigger mechanism. In this way, the contact switch is always located in an independent accommodating chamber, which can prevent external dust particles from causing the contact switch to become stuck, and can prevent the risk of increasing the damage to the contact switch due to the influence of liquid or humid air, thereby improving the working reliability of the contact switch and extending the service life of the contact switch.
